Thanks for keeping this dialogue tight, sometimes one has to state that which is not obvious to some.
For clarity the site owner has 100% control over who is appointed developer, which deals with any conflict of interest issues i.e there won't be any !
As for street names, then again the initiative lies with the site owner, who would in a normal process approach the local authority planners with suggestions & enter into a dialogue thereafter, as local authority approval is required. Subject to conflict of similar names nearby, then they should be sympathetic to names that have relevance to previous use of the land.
